【摘要】 GPS数据采集器是进行GPS相关研究的基本设备,承担接收GPS-OEM板输出数据并保存的任务,在科研、工业、教育、军事等领域都有广泛的应用。目前,在科学实验领域内,国内没有开发相应特性的GPS数据采集系统,所以设计并实现一款GPS数据采集器样机,以满足设备在科学实验领域里GPS数据采集器的实际特性需求(如:在野外工作、外接多种GPS-OEM板类型、具有文件系统、易于扩展功能等特性)是十分有意义的。本论文以科学实验领域内GPS数据采集器的特性需求为出发点,以需求分析、设计方案、设备实现过程、结果测试四部分为内容主线,结合考虑设备的便携性、通用性、具有文件系统、功能可扩展四个特性,最终完成设备样机的搭建、运行和测试。论文具体工作如下:首先,针对科研领域对数据采集器的需求进行分析,得出此次设计以嵌入式系统为设备核心的基本方案。其次,在基本方案的基础上,提出了通过以嵌入式系统-ARM微控器和SD储存卡为硬件核心,UC/OS-II实时操作系统和文件系统为软件核心的具体设计方案,并阐述了设备的硬件和软件实现步骤和方法。再次,针对数据采集器需要进行应用扩展的特性,设计一款基于数据采集器的定位型接收机,使用户为数据采集器增加功能时有范式可依。最后,对数据采集器及其应用进行测试并对测试结果进行分析。论文通过以上研究和实践,设计和实现了一种基于嵌入式系统ARM和SD卡设计的GPS数据采集器,设备具有便携性、通用性、具有文件系统、易于扩展功能的特性,满足了科学实验领域内GPS数据采集器特性的要求。通过运行测试,得到的结果表明,在科学实验领域内,相比同类设备,此次设计同时具有通用性、便携性、具有文件系统、易于扩展功能的优点,达到了的设计预期,满足实际需求。更多还原

【Abstract】 GPS data collector is the basic technology of developing GPS receiver and bears the responsibility for receiving and storing the GPS data which is output by GPS-OEM board. The meaning of this design is that develop a GPS data collector base on embedded system for the requirement of GPS data collector in science experiment (such as field work, variable type of GPS-OEM board, rapid multi-user shared data, easy to extend the function).This paper begins with the GPS data collector in science as its starting point and considers from the portability, universality, data sharing, and function extension. Give the design thoughts and design plan of data collector through analyzing the requirement of GPS data collector equipment. This paper’s task is:First, arrive at the basic plan that embedded system as the core through analyzing the requirement of data collector in science experiment.Second, propose the detailed plan on the base of the basic plan and elaborates the realization processes of hardware and software of the equipment. In the detailed plan, the hardware core is ARM Micro-controller unit and SD memory cards and the software core is UC/OS-Ⅱreal time operating system and file system.Finally, test the data collector and its application and analysis the result of test.Through the above study and practice achievement, provide a GPS data collector plan which based on ARM and SD cards. Test results of the equipment show that in the science experiment, this design has the advantage of portability, universality, data sharing and easily extending function. It reaches expected effect.更多还原
